Step 4: The Stencil

Step 5: Thats it.

I've attached the final blend, so you can look at it as well as each part separately as an .stl file, which are all printable.

Graffiti however cool it may be, is frowned upon by the man, so if you do decided to display your artwork publicly or spruce up the boring neighborhood you should do it in a way that's easy, quick, and simple. That's where my invention comes into play.

Step 1: Welcome

Welcome to the brand new world of 3d printed stencils.
By printing your stencils via a 3d printing service instead of cutting them out laboriously like some dolt, you can have razor sharp edges and a wide range of designs. Plus the stencils you produce will be strong, sturdy and dam impressive.

What the spray can stencil attachment will allow is for you to take your artwork to a whole new level, via 3d printing and a free modeling program called blender.

Step 2: Doubletake

If you haven't looked at my other instructables yet, I urge you to do so because you'll find many links explaining how to use blender.

I've attached a model of a simple spray can if you would like to follow along.

It will allow you to make your own design that you can get printed if you'd like, because the concept is fairly simple.

Step 4: The Stencil

Either you can put it as a background image, or apply it as a texture, (sizing is required). Either way should work fine, because you should be working with a singular plane that's highly subdivided, so you can easily extrude it to the desired thickness later, which happens in this case to be .1cm.

You need to make the areas where the paint will pass void of material, this can be accomplished by moving vertices and deleting edges. If you have any questions feel free to ask.

Sorry, but lemonie's right, this won't work. Most of the paint will be wasted and what does get through the stencil will barely apply a haze of color to the target.

For stealth stencils, people have often cut stencils out of a stiff material and then attached those to grocery bags with the bottoms cut out. Pizza boxes also work really well. Both options let you hide the can as an extra bonus.

The most important aspect is something that isn't even tangible: acting like you're supposed to be doing it. Put on white coveralls and just go to it.

It should still work if there's a slight gap, though not as well if there was no gap at all. This design wont allow for flush contact though I don't see why someone couldn't redesign it to eliminate the gap that's caused by bracket that holds the stencil.
